India’s Reliance Infrastructure is scouting for an international joint venture-cum-technology partner in Russia to locally manufacture nuclear-powered submarines and stealth warships at Pipavav in Gujarat. Reliance Infrastructure has the 18 percent stake in Pipavav Defence & Offshore Engineering. The Reliance Infrastructure is keen to finalise an international technology partner at the earliest as it is likely to pitch for the India’s Rs 60,000-crore defence contract for locally manufacturing six nuclear submarines.
